This hazardous weather outlook is for eastern Utah and western
Colorado.

.DAY ONE...Today and Tonight

Thunderstorm development can be expected this afternoon though
drier air in place should lead to a lesser coverage of storms in
most areas. The best coverage will be over the San Juan mountains
with storms drifting southward in the valleys. Gusty outflow winds
will be a threat with gusts of 35 to 45 mph possible in some of
the storms. Lightning will always be the highest threat however.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Afternoon thunderstorm development will be possible each day
favoring the mountains through the early week period. Another
push of monsoonal moisture arrives by mid-week which will bring
an uptick in thunderstorm coverage. Any thunderstorm will be
capable of producing gusty outflow winds, heavy rain, small hail
and dangerous cloud-to-ground lightning. Localized flooding may
also become more a threat with the push of moisture by Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will most likely not be needed over the next
24 hours.
